'Easy to See Why Mueller Makes Him Sweat': MSNBC's Nicolle Wallace Explains Why the Russia Probe Is a Major Threat to Trump

As special counsel Robert Mueller's investigation into Russian meddling in the 2016 election and potential collusion with President Donald Trump's campaign hits the one-year mark, MSNBC's Nicolle Wallace explained why the impressive scope and pace of the investigation should terrify the president.

On Thursday's episode of "Deadline: White House," Wallace explained that Trump's lawyer Rudy Giuliani has recently shifted tactics to arguing that a sitting president can't be indicted.

"Not being able to indict a president isn't the same as maintaining that the president is innocent of crimes around possible collusion or obstruction," she said. "And if you look at the scope of people who have been before Mueller's investigators — people like Attorney General Jeff Sessions, Hope Hicks, former Chief of Staff Reince Priebus, Jared Kushner, Steve Bannon, Mike Pompeo and Don McGahn — and if you consider the pace of Mueller's probes and its results, including multiple charges for former campaign Chairman Paul Manafort and guilty pleas from the president's former national security adviser Mike Flynn, his former Deputy Campaign Chairman Rick Gates, and former campaign aide, George Papadopolous, it's easy to see why Mueller makes him sweat."

She continued: "Flynn pleaded guilty to lying to the FBI about his interactions with Russian Ambassador Sergey Kislyak. And Papadopoulos admitted to lying to the FBI about his contacts with individuals connected to Russia. So far, no one's gone down for lying about Canada."
